This invention relates to a Venetian blind, and more particularly acollapsible blind made of woven fabric.

This invention has for its objects to provide a collapsible blind whichhas an ncreased effect of shielding light and in which the elevation andturning of the blind elements can be readily effected. These objects inview, the blind according to this invention comprising a plurality ofblind elements each of which consisting of a piece or pieces of wovenfabric formed into a flat tubular shape and stretched on a skeletonframe, havin loops at both ends, means or sus ndlng sai blind elementsarranged at suita le intervals,

guide rods along which said loops on each element are slidably guided,and means for varying the angle of inclination of the blind elements.

In the accompanying drawings lIlWhlCll several embodiments of theinventionare shown by way of example:

Referring to the drawings, A desi ates a plurality of blind elements,each of w ich is made of a piece or pieces ofwoven fabric formed into aflat tube and stretched on. a skeleton B, and is provided at both endswith loops C. The skeleton B consists of an oblong frame, of which thelongitudinal members are made of steel wire, the ends thereof beingsecured to cross pieces 1.

Reinforcing members 2 are provided at intermediate points of theskeleton in order to keep the parallel arrangement of the side 80members of the skeleton B. Said reinforcing member 2 is made of acorrugated metal strip, and issecured at its ends to the steel wiresforming the side members. The loop C consists of two interconnectedrings, one of 65 which is loosely mounted on the cross piece 1 of theelement A, and the other ring adapted to be engaged by the guide rod orrail E. In the modification shown in Figure 14, the loop C may consistof a single ring pivotally connected to the cross piece 1 by means of apin fixed to the ring.

D designates suspension strips or tapes each secured at the upper end tothe fixed part 3, and to which suspension strip D are secured thelongitudinal edges of the said blind elements A, the latter beingthereby suspended and arranged at suitable intervals in parallelpositions. I

The guide rods E engage with the loops C at the ends of theblindelements A, and serve to uide the movement of the elements A. In or erto minimize the friction between the loops C and the guide rods E and toprevent undue noise during the movement of the blind elements, said uiderods E are provided with a covering 4: o ebonite or hard rubber. Saidcovering 4 is preferably provided on the outer surface with longitudinalgrooves as shown in Figures 7 and 8.

G is a pulling cord connected at its lower end to the lowermost one ofthe blind elements and led upwardl and passed around pulleys 5. This corG when pulled in the direction of the arrow serves to lift the blindelements. Another pulling cord H is con nected to a horizontal bar 6which is attached to the suspension strips D, and is passed aroundpulleys 7. This cord H when pulled in the direction of the arrow servesto elevate one edge of each blind element, thereby varying the angle ofinclination of the latter.

The blind element A is made of tubular fabric or of ordinarily wovenfabric which is sewed into a tubular form. In the modification shown inFigure 15, the element A is formed by two sheets of fabric sewedtogether at both side edges. along the seam 8 to form selvages a. TlllSform has advantages that the suspension strips D can be easily connectedby sewingv to the elements A and that the selvages a withstand againstwear. Plaited extension pieces F are attached to the ends of theelements A and to the lower side of the lowermost element, which exten-'sion pieces contact with the window frame 9 and serve to prevent anylight from stealing in through the gap between the blind and the windowframe.

From the foregoing, it will be seen that inasmuch as each blind elementconsists of double layers of woven fabric, there is not only increasedeifect of shielding light, but also increased heat-proofing andnoise-proofing efi'ect can be attained according to the presentinvention. Moreover, according to the invention, the blind elementconsisting of woven fabric can be readily washed by removing theskeleton therefrom. As the blind element is made of tubular woven fabricstretched on the skeleton consisting of steel wires and reinforcingmetal strips, the blind according to this invention is light in weight,while it is of durable construction;

Furthermore, according to the invention the blind can be readily liftedto the collapsed position by means of a pulling cord, and the angle ofthe inclination of the blind elements can be adjusted at will by asimple and easy operation to vary the amount of light or the amount ofair passing through the window.

\Vhat I claim is:

1. A collapsible blind comprising a plurality of blind elements eachconsisting of a. piece or pieces of woven fabric formed into a fiattubular shape and stretched on a skeleton frame having loops at bothends, means for suspending said blind elements arranged at suitableintervals, guide rod's along which said loops on each element areslidably guided, and means for varying the angle of inclination of theblind elements.

2. A collapsible blind comprising a plurality of blind elementsconnected at suitable intervals by means of suspension strip, each ofsaid elements being formed into a flat tubular shape and having askeleton therein.

3. A collapsible blind comprising a plurality of blind elements, eachelement consisting of a piece or pieces of woven fabric formed into aflat tubular shape and sewed together at both side edges to formselvages, and having suspending strips sewed to said selvages.

4. A collapsible blind comprising a plurality of blind elements made ofwoven fabric formed into a flat tubular shape, each of with said loopsfor 'slidably guiding the blind elements.

6. A collapsible blind wherein each blind elementis providedtat each endwith a loop consisting of interconnected two rings, one of which isfixed to the end of the blind element and the other is passed around theguide rod, so that the blind elements are turnably supported.

7. A collapsible blind comprising a plurality of blind elements, rodsupon which said elements are slidably guided, each of said guide rodsbeing provided with a. covering of ebonite or hard rubber, and surfaceof which is provided with a plurality of longitudinal grooves.

S. A collapsible blind comprising a plurality of blind elements, whereinsuspension strips on one side are connected by a horizontal bar to whichis connected a pulling cord, so that by pulling said cord the angle ofinclination of the blind elements can be varied.

9. A collapsible blind comprising a plurality of blind elements arrangedat suitable intervals and connected by means of suspension strips, andprovided at both sides and lower extremity with plaited fabricscontacting with the window frame.

In testimony whereof I afiix my signature.
